Poor contrast in system settings with dark theme

Whatever dark theme I choose, whether it be Breeze or the default Garuda theme, I get terrible contrast in the system settings app.
The attached screenshots will both demonstrate the issue and show my appearance settings.
I only have this issue in system settings app, and in System Tray Settings, which might actually be the same thing...

You don't have those crappy colors (I admit your screenshots look bad! :frowning: ) outside of SystemSettings/SystemTray?
So you open up Dolphin, Web browser, etc. and no issue there?

I believe you have 2 monitors with different DPIs and potentially scalings.
What if you move the SystemSettings window to the other monitor, does it still display bad contrast?

Dolphin looks great, and so does Firefox and all my other apps.
I have two monitors with different resolution and refresh rate, but the same scaling, which is 100%.
I just moved the SystemSettings window to the other monitor, and it looks the same as on the main monitor.

It's been like that forever or before it worked fine and then after "something" that happened on the machine that you may not know the contrast started to crap up?

You are free to trash this whole thread after you read my answer......

I installed Garuda Xfce like a week ago. Everything worked as expected. Then I installed Plasma desktop on top of it, a couple days ago (with X11, not Wayland) and the problem was there right away.

Actually that's very interesting to know!

I'm not an expert of multiple DMs installed or upgrading from one to another, but I remember reading that having multiple DMs can cause all sort of weird issues.

If you really want to make this work, I'm hoping someone with more knowledge would help.
If you don't need Xfce, one obvious option would be to trash your installation and restart fresh with Plasma. :smiley: But you know that one already for sure.

Good point.
If you make such interventions to the system and don't mention it in the first post, it's a waste of time from those who want to help.

Just closed.
